title: Myxobolus ophiocarae sp. n. (Myxozoa: Myxosporea: Bivalvulida) infecting the gill of wild goby, Ophiocara porocephala (Perciformes: Gobioidei) in Malaysia.
abstract: The authors studied the myxosporean infection of wild gobiid fishes (Perciformes: Gobioidei) in the Merang Estuary of Terengganu, Malaysia, and described Myxobolus ophiocarae sp. n. in Ophiocara porocephala. Several myxosporean plasmodia were found intralamellarly within the gill filaments. The spores differed from those of other Myxobolus species previously recorded on gobiid fishes. They were round in valvular view and lens-shaped in sutural view, and had two equal-sized, pyriform polar capsules with polar filaments having six to seven turns. The spores measured 10.34 × 8.79 × 4.53 μm. The 18S rDNA sequence of M. ophiocarae sp. n., based on a contiguous sequence of 1,789 base pairs, differed from any other Myxobolus spp. in GenBank. Phylogenetic analysis of the 18S rDNA gene revealed that this species showed the closest similarity to Myxobolus nagaraensis, Myxobolus lentisuturalis, and Myxobolus cultus.
